SITE PREPARATION
The dispenser is very heavy. Place it on a sturdy counter or shelf capable of supporting at least 180 lbs. It is
for indoor use only.
Thedispensermusthaveatleastsixinchesofspacebehindit.Thisspaceisneededforairflow,airfilterremoval,
and cleaning. A clearance of at approximately six inches is recommended between the dispenser sides and the wall
or another appliance. The dispenser performs better if not placed near any heating appliance. Leave some space
so the dispenser can be moved for cleaning.

USING THE DISPENSER FOR GRANITA-TYPE PRODUCTS
1. Lift the lid slightly for the selected hopper and slide back to gain access to the hopper.
2. Place the pre-mixed liquid product in the selected hopper.
3. a. Press and release the
(ON/OFF) switch to power on the dispenser.
b. Press and release the Left and/or Right
(ON/OFF) switch to start the Auger Motor.
c. Press and release the
selected hopper.
(OFF/ICE/CHILL) switch and select ICE to begin the cooling process for the
4. Wait for the liquid to freeze to the desired consistency.
HINTS – Bunn-O-Matic recommends that the product in the dispenser be thawed each day, usually overnight.
The ice granules get too large and a consistent product is difficult to maintain if left frozen for an extended
period of time. Set the NIGHT mode for a few hours each night and return it to the DAY mode when the
product has thawed sufficiently. You’ll know it is in the NIGHT mode because the display will indicate NIGHT
MODE.
USING THE DISPENSER FOR COLD LIQUID PRODUCTS
1. Lift the lid slightly for the selected hopper and slide back to gain access to the hopper.
2. Place the pre-mixed liquid product in the selected hopper.
3. a. Press and release the
(ON/OFF) switch to power on the dispenser.
b. Press and release the Left and/or Right
(ON/OFF) switch to start the Auger Motor.
c. Press and release the
(OFF/ICE/CHILL) switch and select CHILL to begin the cooling process for
the selected hopper.
4. Wait for the liquid to cool.
32080 021202

OTHER RECOMMENDATIONS FOR YOUR DISPENSER
•
Whether liquid concentrate or granulated powder, all product must be thoroughly mixed BEFORE adding it
to the hoppers.
•
For best results with granita-type products, use only products with an apparent brix of 12 or higher. Some
products may work with an apparent brix as low as 9. Your experimentation with other products will be the
best guide in this area.
•
•
Keep the pre-mixed liquid product refrigerated. This reduces cooling/freezing time in the dispenser.
Keep the hoppers topped-off during peak serving periods. Add pre-mixed liquid product as it is dispensed.
This reduces the cooling/freezing time and assures you of always having product ready to dispense.
Keep the product level in the hoppers higher than the auger. Air will become entrapped in the mixture
resulting in a clouded foamy consistency.
You may find it beneficial to turn down the ice controls to keep the ice granules from growing too large.
Refer to Programming The Dispenser on page 11 for Setting the Consistency.
Some products freeze at a lower temperature than others. You may notice frost or ice on the hoppers. This
is normal and should not be a concern.
•
•
•
•
Humidity in the air may cause sweating on the outside surfaces of the hoppers. This is to be expected and
should not be a concern. The drip trays beneath the hoppers will capture this and cause it to flow to the
lower drip tray for disposal.
•
Some noises are to be expected during normal operation of the dispenser. By becoming familiar with the
noises made during normal operation, you will be better able to listen for problems.

RECOMMENDED DAILY CLEANING
NOTE – Turn the power OFF to the dispenser before proceeding.

cleaning. Deep scratches could cause leakage around the seal.
10. Place all parts in a clean sink with mild hot water (120°F) and sanitizer solution. Allow all parts to soak for at least
5 minutes. Carefully wash all components with a clean wash cloth in the hot water and sanitizer solution. Use a
clean, soft bristle brush as needed for the smaller components and tight areas. Do not immerse hopper lids. Use
a commercial sanitizer that has 100 ppm of available chlorine with a concentration level of at least 3% available
chlorine (KAY-5 Sanitizer). Follow the sanitizer’s mixing instructions to ensure 100 ppm of available chlorine.
11. Wash the drums, hopper drip trays, top covers, and outer enclosure using a clean wash cloth that has been
dampened in the hot water and sanitizer solution. Pay particular attention to the shaft area and make sure it
is thoroughly cleaned and sanitized.
12. Thoroughly rinse all surfaces with a clean wash cloth that has been dampened with hot water. Wipe dry with
a clean dry wash cloth before reassembling the dispenser.
NOTE – Although most parts are dishwasher safe, they may be affected by the chemicals in some commercial
sanitizing agents. Do not place the hopper nor hopper lids in a dishwasher. Rinse thoroughly before assembly.
